Third year medical student knowledge gaps after a virtual surgical rotation.

INTRODUCTION: This study describes perceived knowledge gaps of third-year medical students after participating in a virtual surgical didactic rotation (EMLR) and shortened in-person surgery rotation during the COVID-19 Pandemic. METHODS: Open-ended and Likert questions were administered at the end of the virtual rotation and inperson-surgical rotation to medical students. Three blinded coders identified themes by semantic analysis. RESULTS: 82 students (51% of all MS3s) participated in the EMLR. Semantic analysis revealed gaps in perioperative management (Post-EMLR:18.4%, Post-Inpatient:26.5%), anatomy (Post-EMLR:8.2%, PostInpatient:26.5%). and surgical skills (Post-EMLR: 43.0%, Post-Inpatient: 44.1%). Students also described gaps related to OR etiquette (Post-EMLR: 12.2%, Post-Inpatient: 8.8%) and team dynamics/the hidden curriculum (Post- Inpatient:26.6%). There was a significant improvement in perceived confidence to perform inpatient tasks after completing the inpatient clinical experience (p ≤ 0.01). CONCLUSION: Virtual interactive didactics for cognitive skills development cannot replace a full clinical surgical experience for third-year medical students. Future curricula should address perceived gaps.

Bursting the Hidden Curriculum Bubble: A Surgical Near-Peer Mentorship Pilot Program for URM Medical Students.

The hidden curriculum of unspoken professional expectations negatively impacts medical student interest in surgery. Medical student mentorship and early surgical exposure have been shown to demystify the hidden curriculum. Although residents and faculty play a vital role, near-peer mentorship may aid in uncovering the hidden curriculum and promoting medical student interest in surgery, especially for those learners who are underrepresented in medicine. We developed and implemented a formalized near-peer mentorship program composed of quarterly small group Surgical Peer Teacher led lessons and one-on-one Surgical Support Team mentorship meetings covering surgical curriculum topics for medical students at an academic medical school. This structured near-peer mentorship model provides a mechanism to demystify surgical culture, increase early access to surgical mentorship, and develop mentorship skills amongst students. This program aims to uncover the surgical hidden curriculum to improve surgical career support and interest among medical students with less exposure and access to physician role models. This longitudinal mentorship model is student-run and can be easily adapted to enhance existing support models at medical schools. Future studies will evaluate utilization, impact on surgical specialty interest, and efficacy in demystifying the surgical hidden curriculum.

Instilling Resiliency in Surgical Education: The Benefits of Longitudinal Medical Student Learning.

The longitudinal clerkship has been recognized as an innovative, unique model in medical education that demonstrates significantly higher student and preceptor satisfaction with comparable long-term outcomes like performance on standardized examinations. At the center of this model is the student-preceptor relationship, which promotes effective student-directed learning and personal and professional relationships with established faculty mentors. The University of California, San Francisco (UCSF) has two clerkships models: a traditional or "block" model consisting of 2-month sequential clinical rotations in seven core clerkships, and a longitudinal model that integrates parallel out-patient clinical experiences over the entire year with one-on-one faculty preceptors from each core discipline with focused 2-week intensive inpatient rotations. In the setting of the Covid-19 pandemic beginning in Spring of 2020, this arrangement allowed for a natural experiment to evaluate the resiliency of the respective models in the face of unprecedented disruptions in education and healthcare delivery. As described in this perspective, both clerkships required rapid pivots; however, students enrolled in the longitudinal clerkship were more likely to develop stronger relationships with surgical faculty and felt more prepared for making career choices. Medical school curricula may benefit from incorporating longitudinal components, as this model provided flexibility and fostered greater faculty-student mentorship in the setting of disruption to medical education.

Where Do We Go From Here? Assessing Medical Students' Surgery Clerkship Preparedness During COVID-19.

INTRODUCTION: The impact of COVID-19 on surgical education has been profound, and clinical learning experiences transitioned to virtual formats. This study investigated the impact of virtual experiences created to facilitate learning during the pandemic for medical students. METHODS: We performed a cohort study to determine the perceived clinical preparedness for medical students enrolled in the preclinical surgery pilot course, surgical Extended Mastery Learning Rotation (EMLR), and longitudinal surgical clerkship (LC). The preclinical surgery pilot course took place before COVID-19 disruptions, and the EMLR and LC experiences took place virtually. Specialty choice was examined in the EMLR and LC cohorts. Performance on the NBME surgical assessments was analyzed among students enrolled in the traditional clerkship and pandemic-disrupted courses and compared to national data using a two-sample t-test. RESULTS: Compared to preclinical students, EMLR and LC students demonstrated improvements in their perceived surgical clerkship readiness. After the 3-week EMLR course, in the setting of completing only one-third of the clerkship year, students had an average NBME Surgical Self-Assessment Exam score of 72 (SD 12), comparable to the national average of 71 (SD 9) p = 0.33. The average shelf exam score for students (N = 24) enrolled in the traditional clerkship (block 1), prior to COVID-19, disruptions was 66 (SD 9) compared to an average score of 69 (SD 9) for the longitudinal clerkship students (N = 20) that took the shelf exam later in the year (p = 0.36). COVID-19 disruptions did not affect specialty choice. All LC students have decided on a specialty; 50% nonsurgical and 50% surgical. From the EMLR cohort, 36% and 38% plan to pursue surgical and nonsurgical specialties, respectively, with 26% still undecided. CONCLUSIONS: Courses were well-liked and will be implemented in future clerkships. Surgical educators demonstrated flexibility and creativity in the development of the EMLR. Despite COVID-19 disruptions, medical students made progress in their clinical skills and foundational science knowledge. COVID-19 disruptions did not appear to impact specialty choice.

Near-Peer Learning During the Surgical Clerkship: A Way to Facilitate Learning After a 15-Month Preclinical Curriculum.

OBJECTIVES: To investigate the performance and perspectives of third-year medical students (MS3s) participating in near-peer learning (NPL) sessions during their core surgical clerkship following a 15-month preclerkship curriculum. DESIGN: An evaluation study of 7 NPL sessions developed and implemented by fourth-year medical students (MS4s) held from March 2019 to February 2020. MS4s taught 1-2 sessions per rotation that included test taking strategies, illness script development, radiology review, case-based multiple-choice questions, and rapid review. Participants completed a questionnaire with 11 seven-point Likert and open-ended questions after each session. Analyses included quantitative comparison of shelf score averages between NPL participants and nonparticipants and qualitative content analysis for open-ended questions. SETTING: Surgical clerkship at the University of California, San Francisco. PARTICIPANTS: Forty-eight (32%) MS3s participated, with an average attendance of 10 students per rotation. Thirty-three (69%) participants completed the questionnaire. RESULTS: MS3s enjoyed the session (6.9 ± 0.4), improved their knowledge (6.8 ± 0.5), and felt more prepared for the surgery shelf examination (6.5 ± 0.6). MS4 leaders found that MS3s always wanted radiology review, and their interest in test taking strategies and illness script development declined across the clerkship year. Participants had lower shelf exam scores compared to nonparticipants (68.1 vs 71.4, respectively; p = 0.04, ES = 0.03). Shelf exam scores increased over time in both cohorts. Each group had 2 shelf exam failures. Qualitative analysis suggests that MS3s appreciated the NPL's tailored approach and exam demystification, with a desire for increased NPL integration into the clerkship. CONCLUSION: Students participating in NPL were satisfied with the sessions. Participants may have been students who struggled as indicated by shelf exam scores and appreciated the support. The shift in preferred topics across the blocks reflects the students' development during clerkships. Near-peer teachers should adjust sessions over time to fit students' evolving needs.

"There Is a Lot of Change Afoot": A Qualitative Study of Faculty Adaptation to Elimination of Tiered Grades With Increased Emphasis on Feedback in Core Clerkships.

PURPOSE: Medical schools responding to challenges with fairness, equity, learning environments, and student wellness have reconsidered clerkship grades. This study used the Concerns-Based Adoption Model (CBAM) to explore how faculty responded to a change in the approach to assessment from focus on grades toward focus on feedback. METHOD: This qualitative study used an inductive approach to analyze data from semistructured interviews with teaching faculty and education leaders at University of California, San Francisco, School of Medicine 6 months following the elimination of traditional tiered clerkship grades. Participants were recruited in 2019 using purposive sampling. Interview questions addressed participants' perceptions of the new approach to assessment and grading that emphasizes assessment for learning, including advantages and concerns. The authors analyzed data using thematic analysis informed by sensitizing concepts from CBAM. RESULTS: Nineteen faculty participated (11 medicine, 8 surgery). Faculty expressed optimism about the impact of the change on their clinical educator roles and sought faculty development to enhance feedback and assessment skills. Perceived benefits to students addressed learning and wellness, with concern for students' motivation and professional development. Faculty shared uncertainty about their roles and larger systemic consequences involving the residency match and institutional reputation. Participants acknowledged that traditional grading is imperfect, yet felt a departure from this system represented significant culture change. CONCLUSIONS: Faculty perceptions of the assessment and grade change in 2 large departments demonstrated tensions around grading. Their descriptions of change as an ongoing process aligned with CBAM and required them to consider new approaches and perspectives. While discourse about assessment and grading frequently focuses on learners, these findings support institutional consideration of the impact of changes in assessment on teaching faculty.

Surgery Clerkship Curriculum Changes at an Academic Institution during the COVID-19 Pandemic.

PROBLEM: The COVID-19 pandemic has suspended the surgery clinical clerkship for third-year medical students at numerous institutions across the world. As a result, educators and students have adapted rapidly. There is a paucity of precedents regarding urgent and brusque formal curricular changes for medical students enrolled in surgical clinical rotations. APPROACH: The University of California, San Francisco Department of Surgery created a surgically focused extended mastery learning rotation (EMLR). The surgery clerkship leadership designed a curriculum consisting of multiple learning strategies compatible with virtual learning environments. The primary aims of the newly developed EMLR were to help students consolidate their foundational science knowledge before their return to clinical medicine in an altered learning environment. The EMLR is currently underway, and further studies are necessary to evaluate its effectiveness.

Upper Gastrointestinal Endoscopy in an Academic General Surgical Program: Implications for Acute Care Surgeons.

Background. Esophagogastroduodenoscopy (EGD) is an important tool in the evolving specialty of acute care surgery (ACS). Understanding the types of nonelective EGDs performed by ACS groups is important for the development of ACS programs and the training of future general surgeons. Methods. We conducted a retrospective review of all EGDs performed by ACS surgeons at a single urban academic center over a 5-year period (January 2013-December 2018). Results. A total of 495 EGDs were performed, of which 129 (26%) were urgent, nonelective procedures. Patients who underwent urgent EGD were younger than those who underwent elective procedures (median 55 vs 60 years, P = .03), had higher American Society of Anesthesiologists (ASA) classes (median ASA 3 vs 2, P = .0002), and longer hospital stays (median 5 days vs 0 days, P < .0001). The most common indications for urgent endoscopies were the management of leak, dysphagia, or stenosis in patients with a history of foregut surgery, followed by the management of esophageal perforation. The success rate of endoscopic therapy was high (median 88%, interquartile range (IQR) 78-89%). However, some patients required multiple interventions (median 1, IQR 1-3), and patients treated for leaks were less likely to be successfully treated with endoscopic therapy alone than patients treated for other indications (success rate 65% vs 88%, P = .003). Conclusions. Our experience suggests that EGD has an important role in current ACS practice and that endoscopic management is safe and effective in a range of urgent surgical scenarios. Future ACS surgeons should be facile with endoscopic techniques.

Predictors and Outcomes of Paramedian Incisional Hernia After Anterior Spine Exposure.

BACKGROUND: Anterior exposures for lumbar spine surgery are increasingly common for treating various spinal pathologies. A retroperitoneal approach via a paramedian incision has grown rapidly in popularity, but little is known about the risk of incisional hernia development with this technique. We sought to assess the incidence of paramedian incisional hernia development and identify risk factors that are associated with occurrence. MATERIALS AND METHODS: We conducted a retrospective review of all patients who underwent anterior lumbar spine exposure by a paramedian approach between 2012 and 2017 at a single, tertiary medical center. The primary outcome was the development of postoperative paramedian incisional hernia. RESULTS: Of the 735 patients included in the study, 445 (60.5%) were women, and the mean (standard deviation) age of all patients was 60 y (12.4). Nearly all (97.4%) paramedian approaches were performed with a vascular surgeon present. Median follow-up time was 10 mo (interquartile range 3.5-19.9). Postoperative paramedian hernia developed in 20 patients (2.7%), of which 14 underwent repair. The mean (standard deviation) size of the hernia was 13.5 cm (5.5); 9 of 14 (64%) were repaired with synthetic mesh, whereas 3 of 14 (21%) required bowel resection. On multivariate analysis, risk factors associated with hernia development were male gender (0.045), higher American Society of Anesthesiologists class (0.039), history of abdominal surgery (P = 0.013), and postoperative intensive care unit admission (P = 0.02). CONCLUSIONS: A paramedian approach for anterior lumbar spine exposure resulted in a low rate of incisional hernia with minimal morbidity. Surgeons involved in these collaborative procedures should consider the risk factors that predispose patients to develop these hernias.

Subcutaneous Fat Fibrosis Links Obesity to Insulin Resistance in Chinese Americans.

Objective: Type 2 diabetes presents at a lower body mass index (BMI) in Chinese individuals than in white individuals. We sought to determine the role of subcutaneous adipose tissue (SCAT)-intrinsic factors, vs BMI or adiposity per se, in the vulnerability of Chinese individuals to obesity-associated impairment of insulin sensitivity. Research Design and Methods: Thirty-two Chinese and 30 white men and women from a cohort in the San Francisco Bay Area underwent anthropometric measurements, body composition (dual-energy X-ray absorptiometry) analyses, and measurement of fasting plasma glucose and insulin. Forty-eight also provided abdominal SCAT samples for transcriptional and biochemical analyses of tissue fibrosis. Results: BMI correlated with total body fat in white (r = 0.74, P < 0.001) but not Chinese individuals, whereas BMI correlated with visceral adipose tissue (VAT) accrual in both ethnicities (r = 0.88 and 0.81, respectively; P < 0.01). Insulin resistance (homeostatic model assessment of insulin resistance) worsened with VAT mass, but not total body fat, in Chinese subjects (r = 0.63, P < 0.01), whereas it worsened with both in white individuals. By contrast, SCAT mRNA levels of genes encoding profibrotic proteins rose remarkably along with both BMI and VAT mass in Chinese but not white subjects. Similarly, SCAT levels of hydroxyproline, an indicator of tissue collagen content that correlated with increasing VAT mass, were higher in Chinese vs white subjects, particularly in the setting of relative insulin resistance. Conclusions: Our findings dissociate BMI from adiposity in Chinese individuals and instead highlight SCAT fibrosis as a process linked to visceral adiposity and insulin resistance in this group.

Primary Colonic Lymphoma.

Primary colonic lymphoma is a rare large bowel malignancy usually found in the cecum or rectosigmoid junction. Because of its non-specific symptoms, patients often present with advanced disease requiring surgical intervention. Nevertheless, resection followed by chemotherapy appears to offer the best prognosis.

Expanded indications for bariatric surgery: should patients on chronic steroids be offered bariatric procedures?

BACKGROUND: Patients who take chronic corticosteroids are increasingly referred for bariatric surgery. Little is known about their clinical outcomes. OBJECTIVE: Determine whether chronic steroid use is associated with increased morbidity and mortality after stapled bariatric procedures. SETTING: American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. METHODS: All patients who underwent laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass and were reported to the ACS-NSQIP from 2011 to 2013 were reviewed. Patients were grouped based on type of surgery and history of chronic steroid use. Primary outcome measures were mortality and serious morbidity in the first 30 days. Regression analyses were used to determine predictors of outcome. RESULTS: Of 23,798 patients who underwent laparoscopic sleeve gastrectomy and 38,184 who underwent Roux-en-Y gastric bypass, 385 (1.6%) and 430 (1.1%), respectively, were on chronic steroids. Patients on chronic steroids had a 3.4 times increased likelihood of dying within 30 days (95% confidence interval 1.4-8.1, P = .007), and 2-fold increased odds of serious complications (95% confidence interval 1.2-2.3, P = .008), regardless of surgery type. In multivariate regression, steroid usage remained an independent predictor of mortality and serious complications. CONCLUSION: In a large, nationally representative patient database, steroid use independently predicted mortality and serious postoperative complications after stapled bariatric procedures. Surgeons should be cautious about offering stapled bariatric procedures to patients on chronic steroids.

Peer video review and feedback improve performance in basic surgical skills.

BACKGROUND: Incorporation of home-video assessments allows flexibility in feedback but requires faculty time. Peer feedback (PF) may provide additional benefits while avoiding these constraints. METHODS: Twenty-four surgical interns completed a 12-week skills curriculum with home-video assignments focused on knot tying and suturing. Interns were randomized into 2 groups: PF or faculty feedback (FF). Peers and faculty provided feedback on home videos with checklists, global rating, and comments. Learners' skills were assessed at baseline, during, and at the conclusion of the curriculum. Performance of the 2 groups as rated by experts was compared. FF and PF were compared. RESULTS: Both groups improved from baseline, and the highest rated scores were seen on their home-video assessments. The PF group performed better at the final assessment than the FF group (effect size, .84). When using a checklist, there was no significant difference between scores given by peers and faculty. CONCLUSIONS: The PF group performed better at the final assessment, suggesting reviewing and analyzing another's performance may improve one's own performance. With checklists as guidance, peers can serve as raters comparable to faculty.

A prospective, randomized controlled trial of single-incision laparoscopic vs conventional 3-port laparoscopic appendectomy for treatment of acute appendicitis.

BACKGROUND: Proponents of single-incision laparoscopic surgery (SILS) claim patients have less pain, faster recovery, and better long-term cosmetic results than patients who undergo multiport laparoscopy. However, randomized comparisons are lacking. This study presents the results of a prospective randomized trial of SILS or 3-port laparoscopic appendectomy. STUDY DESIGN: Adults with uncomplicated acute appendicitis were randomized 1:1 to either SILS or 3-port laparoscopic appendectomy. The primary end point was early postoperative pain (measured by opiate usage and pain score in the first 12 hours). Secondary end points were operative time, complication rate (including conversions), and recovery time (days of oral opiate usage and return to work). After 6 months, body image and cosmetic appearance were assessed using a validated survey. RESULTS: The trial was planned for 150 patients, but was halted after 75 patients when planned interim analysis showed that SILS patients had more postoperative pain (pain score: 4.4 ± 1.6 vs 3.5 ± 1.5; p = 0.01) and higher inpatient opiate usage (hydromorphone use: 3.9 ± 1.9 mg vs 2.8 ± 1.7 mg; p = 0.01) than 3-port laparoscopy. Operative time for SILS averaged 40% longer (54 ± 17 minutes vs 38 ± 11 minutes; p < 0.01). Only 1 SILS case was converted to 3-port. There were no significant differences in length of stay, complications, oral pain medication usage after discharge, or return to work. After 6 months, body image and cosmetic appearance were excellent for both groups and indistinguishable by most measures. However, 3-port patients reported better physical attractiveness (4.0 ± 0.4 vs 3.8 ± 0.4; p = 0.04) and SILS patients reported better scars (score 18.4 ± 2.7 vs 16.4 ± 3.0; p < 0.01). Results are reported as mean ± SD. CONCLUSIONS: Single-incision laparoscopic surgery appendectomy resulted in more pain and longer operative times without improving short-term recovery or complications. Long-term body image and cosmetic appearance were excellent in both groups.

Laparoscopic sleeve gastrectomy is safe and efficacious for pretransplant candidates.

BACKGROUND: Morbid obesity is a relative contraindication for organ transplant because it is associated with higher postoperative morbidity and mortality. The safety and efficacy of laparoscopic sleeve gastrectomy (LSG) as a weight loss method for patients awaiting transplant has not been examined. METHODS: A retrospective review was performed on morbidly obese patients awaiting liver or kidney transplant who underwent LSG from 2006 to 2012. Data included patient demographic characteristics, operative details, 30-day complications, percentage of excess weight loss, postoperative laboratory data, and status of transplant candidacy. RESULTS: Twenty-six pretransplant patients underwent LSG. The mean age was 57 years, and 17 (65%) were women. Six patients had end-stage renal disease, and 20 patients had end-stage liver disease. The preoperative mean body mass index was 48.3 kg/m(2) (range 38-60.4 kg/m(2)). There were no deaths, and there were 6 postoperative complications: 2 superficial wound infections, 1 staple line leak, 1 postoperative bleed requiring blood transfusion, 1 transient encephalopathy, and 1 temporary renal insufficiency. The mean percentage of excess weight loss at 1, 3, and 12 months was 17% (n = 24/26), 26% (n = 23/26), and 50% (n = 18/20), respectively. All patients met our institution's body mass index cutoffs for transplantation by 12 months after the procedure. One patient's renal function stabilized, and he was taken off the transplant list. Eight patients eventually underwent solid organ transplant. Six received liver transplants, 1 patient received a combined liver and kidney transplant, and 1 received a kidney transplant. The mean time between LSG and transplant was 16.6 months. CONCLUSIONS: This is the largest case series involving LSG in patients awaiting solid organ transplantation. LSG is well tolerated, is technically feasible, and improves candidacy for transplantation.
